使用Python 2.7.14通过pip安装geopandas时出现egg_info错误码1问题

Hey there, let’s work through this annoying error you’re hitting when trying to install geopandas on Python 2.7.14. That python setup.py egg_info failure is almost always tied to either outdated packaging tools or incompatible dependency versions—and since Python 2.7 reached end-of-life years ago, geopandas has dropped official support for it. But don’t worry, we can still get it up and running with a few targeted steps.

Step 1: Upgrade pip and setuptools to their last Python 2.7-compatible versions #

Older versions of pip and setuptools often cause egg_info errors because they don’t handle modern package metadata correctly. Run these commands to get the newest versions that still support Python 2.7:

pip install --upgrade pip==20.3.4
pip install --upgrade setuptools==44.1.1

Step 2: Install compatible versions of geopandas’ dependencies #

Geopandas relies on libraries like Shapely, Fiona, PyProj, and Pandas—all of which have stopped supporting Python 2.7 in newer releases. Install these specific versions first:

pip install shapely==1.6.4.post2
pip install fiona==1.8.20
pip install pyproj==1.9.6
pip install pandas==0.24.2

Each of these is the final version of that library that works with Python 2.7, so they’ll play nicely together.

Step 3: Install the last Python 2.7-compatible geopandas release #

Now that all dependencies are in place, install the final version of geopandas that supports Python 2.7:

pip install geopandas==0.8.2

Troubleshooting: Missing system libraries #

If you still hit errors, you might be missing system-level libraries that the Python packages rely on. For example:

• On Ubuntu/Debian-based Linux systems, run this to install required system packages:

  sudo apt-get install libgdal-dev libgeos-dev libproj-dev
  

• On Windows, look for pre-compiled binary wheels for the dependency packages (like Fiona and Shapely) that are built for Python 2.7. You can install these local files directly with pip install /path/to/wheel-file.whl.
